Gridman

Gridman (グリッドマン, Guriddoman) is a Hyper Agent from the Hyper World and the titular hero of SSSS.GRIDMAN and GRIDMAN UNIVERSE.

~!In SSSS.GRIDMAN, he chose Yuuta Hibiki as his host to stop Alexis Kerib in order to save Akane Shinjou. However, the injuries he sustained from the fight against Alexis resulted Gridman split into six fragments. Whereas Gridman's master fragment resided within an old computer aptly named "Junk", Four of the fragments spawned new Hyper Agents that became both hosts of said fragments and new assist weapons at the simulated city while the last one ended up possessing his new partner Yuuta, resulting the latter's seemed amnesia.!~

~!In GRIDMAN UNIVERSE, his power of creation was being manipulated by a sentient kaiju named Mad Origin, which resulted in the creation of Kaiju using the Hyper Agent's thoughts for the purpose of harvesting the negative thoughts of humankind from various universes. Multiple universes were trapped inside Gridman's true form, resulting in a chaotic overlapping between universes akin to The Big Crunch. He was ultimately saved by Yuuta Hibiki and Akane Shinjou with the help of the imprisoned Alexis Kerib!~
